On generalized kinematic hardening theory of plasticity

Ingenieur-Archiv, 1975
An isotropic theory of plasticity is proposed in which expansion, rotation and translational movement of the yield surface are taken into account. The properties of the anisotropic parameters are investigated for some measured data. The incremental constitutive equation is then derived.

On modelling of kinematic hardening for ratcheting behaviour

Nuclear Engineering and Design, 1995
Abstract A kinematic hardening rule is formulated on the assumption that each component α i of back stress has a critical state for its dynamic recovery to be fully activated. The rule has a feature that only the projection of plastic strain rate to the direction of α i contributes to the dynamic recovery.

Nonlinear kinematic hardening in coupled thermoplasticity

Materials Science and Engineering: A, 2009
Paper deals with permanent deformation of metals within nonisothermal environment. As it is generally known, metals are easier shaped if the specimen in heated. Furthermore, dimensions of an object also change with temperature variation. In that way, thermal effects influence mechanical behavior.

On kinematic hardening and large plastic deformations

International Journal of Plasticity, 1986
The model of physically linear kinematic hardening is investigated in view of its convenient generalization to large strains. This generalization implies the definiton of differential operators in the form of objective tensor derivatives. It has been shown in the literature that an inconvenient choice of the time derivatives leads to a non- monotonic ...

Expansion of a hole in a disk with kinematic hardening

International Journal of Mechanical Sciences, 1969
Abstract A complete solution is obtained for the enlargement of a circular hole in a disk of initial thickness h 0 = αr n 0 , where α and n are constants, using Prager's kinematic hardening law with Tresca's yield function and its associated flow rule.

Kinematic hardening model for overconsolidated clays

Computers and Geotechnics, 2001
Abstract The proposed model puts a particular emphasis on accurate simulation of stress-strain behaviour of overconsolidated clays both within the small strain region of high stiffness and during the large-scale yielding. To achieve this, the model utilizes existing formulations which proved to be successful in description of clay behaviour in these ...

Shakedown for systems of kinematic hardening materials

1995
The paper deals with the shakedown of systems with kinematic hardening materials. Analytical, numerical and experimental methods to solve shakedown problems will be introduced and discussed. Some examples are treated with these methods. Comparison shows that the results of these methods are in good agreement.

An Assessment of Kinematic Hardening Thermal Ratcheting

Journal of Engineering Materials and Technology, 1974
Analytical comparisons are made between the thermal ratcheting response of a kinematic hardening material, a perfectly plastic, and an isotropic hardening material for a two-element assembly. Significant differences were found in the range of mechanical and thermal loading for which ratcheting occurred and the magnitude of the strain accumulation when ...
